The transverse nasal line: an embryonic fault line.
The transverse nasal line has long been neglected and frequently overlooked. This narrow pink or hyperpigmented line or groove extends transversely between the upper two-thirds and the lower third of the nose. It is often hereditary and may be the locus of comedones and milia. Eighteen examples are reported by us, along with a possible embryological interpretation.
